Official ECB-900 Series Description. Introducing the latest additions to the ECB-900 Series of EDIFICE metal chronograph models with advanced features and functions that allow linking with your smartphone. These new models feature digital displays at 12 o’clock and 9 o’clock, which team up with the analog indications to show information in an easy-to-understand format. Establishing a Bluetooth connection between these watches and a smartphone ensures accurate timekeeping, including summer time switching, in virtually any country in the world. A phone can also be used to configure a variety of watch settings.

A motorsports inspired 1/1000-second stopwatch comes with memory for 200 lap time records, and recording a lap time causes the lower right dial to indicate the average speed. A smartphone app lets you select from more than 300 cities for your World Time City, and simplifies alarm and countdown timer settings.
These watches also come with Super Illuminator, which uses high-brightness LED illumination that automatically illuminates both the analog face and the digital displays are automatically illuminated whenever you angle the watch towards your face where lighting is dim. This impressive collection of advanced features and functions is powered by a solar power system, with a CASIO-original shade dispersing solar panel that minimizes shading from the watch hands for highly efficient power generation. The result is uninterrupted, reliable operation without the need for periodic battery replacements.
All of this and much more makes EDIFICE a leader in the 1/1000-second world of modern motorsports.

EDIFICE Design. Bold, fascinating forms and fine details, combined with simple styling that brings out the essence of metal, give birth to products with clearly designed identities.

Drawing and modeling. A prototype is produced based on a sketch using CAD and a 3D printer. A bold design concept takes shape.

Forged stainless-steel case. After forging and heat treatment of the stainless-steel material, precision machining is conducted to complete the boldly designed case form.

Polished finishing. Polish finishing by the hands of skilled craftsmen produces beautiful mirror surfaces on the forge-cast stainless-steel case.

Tough Solar. This original solar power system transforms even weak light from sources such as fluorescent lamps into ample energy to provide stable operation of various high-load functions.

Smartphone Link. Linking the watch to a smartphone provides access to the correct time, not only in the current location but over 300 cities around the world. Alarm setting and control over various other functions from the smartphone enhance operability to an unprecedented high level.

Dual Dial World Time. A dial on the face of the watch always shows the current time in another zone whenever you need it. A sub-dial also indicates a.m. or p.m. at a glance. You can use the smartphone app to select from among 300 cities.

LED Light (Super Illuminator). A high-brightness LED illuminates the dial with bright light to improve visibility remarkably at night and in dimly lit environments.
